Abstract

The invention discloses a low-power sine wave motor, which comprises a housing and a hall circuit board, wherein a rotor (1) and a stator, which cooperatewith each other, are arranged in the housing; a counterweight groove and a magnetic steel caulking groove (5) are sequentially formed in the rotor (1) from inside to outside; the counterweight groove and the magnetic steel caulking groove (5) are formed along the circumferential direction of the rotor (1); a counterweight block (4) is arranged in the counterweight groove; magnetic steel (3) is embedded into the magnetic steel caulking groove (5); a rotating shaft through hole is formed in the hall circuit board; the hall circuit board is arranged on the inner surface of the housing; and meanwhile, a rotating shaft of the rotor (1) passes through the rotating shaft through hole in the hall circuit board. The motor is good in operation, long in service life, low in noise and high in torque.

Description

technical field [0001] The invention relates to a sine wave motor and belongs to the field of motors. Background technique [0002] The market is mainly square wave motors, which use magnetic steel on the surface of the rotor. After working for a long time, the motor heats up quickly, and high temperature is easily generated inside, which causes the magnet steel to demagnetize, and the efficiency gradually decreases, which affects the performance of the motor, easily causes damage to the motor, and increases the cost of after-sales service. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a low-power sine wave motor, which not only has good operation, long service life, but also low noise and large torque. [0004] To achieve the above object, the technical solution adopted in the present invention is: [0005] A low-power sine wave motor, including a casing and a Hall circ...
